Spectrum and scattering function of the impulsive discrete Dirac systems

Authors: ELGIZ BAIRAMOV, ŞEYDA SOLMAZ

Abstract: In this paper, we investigate analytical and asymptotic properties of the Jost solution and Jost function of the impulsive discrete Dirac equations. We also study eigenvalues and spectral singularities of these equations. Then we obtain characteristic properties of the scattering function of the impulsive discrete Dirac systems. Therefore, we find the Jost function, point spectrum, and scattering function of the unperturbed impulsive equations.

Keywords: Dirac systems, Jost solution, scattering function, eigenvalues
